How often does Kitty drink milk? every day
go skating? twice a week
go boating? once a month
play ping-pong? three time a week
教学小贴士
Let’s learn more部分的短文主要学习的是怎样描述第三人称的活动频率。关于频率的描述，在Let’s talk部分只学了every day。在这一篇课文中主要学习类似的短语：nine hours every night, twice a week, once a month, three times a week。教师可拓展讲解频率的表述，如：在表示“一个时间 段里某事发生几次”时，先说“多少次”再说“时间段”。一次once，两次twice，三次以上要用“数词+ times”来表示次数。
(3) 巩固活动：听读练习
a. 教师带领学生一起浏览Read again and answer the questions部分的五个问题。教师可以通过请同学单独读问题、集体读、男女生读等不同的方法来引起学生注意。
b. 教师播放Let’s learn more部分的录音。播放第一遍时，可让学生先感知短文中的语音语调以及停顿断句。播放第二遍时，教师可逐句播放，让学生模仿音频中的语音语调跟读本部分内容。

它没有腿和胳膊。Isn't she right? 难道她不对吗?该句是一个一般疑问句的否定形式, 也称为否定疑问句, 这种句式经常用来表达提问者对某事的赞美、惊讶、失望、怀疑等情感。否定疑问句的答语在形式上与一般疑问句的答语一样, 若与事实相符的都用Yes, 不相符的都用No, 但翻译成汉语时, Yes要译成“不”, No要译成“对/是的”。— Isn't it a beautiful flower?它不是一朵美丽的花吗?(赞美)
— Yes, it is. 不, 它是。
— Don't you believe him? 你难道不相信他吗?(惊讶)
